I got this IBM 1390131 virtually for free. Unfortunately the connection cable has been cut, see pictures below. It used to have a DIN connector but a PS/2 should work fine as well. Does anyone know which pin of a PS/2 plug I have to solder to which contact of the IBM connector to fix it?

I can sell you a regular cable for 15€ inkl. shipping to the netherlands, or an extra long one for 20.
I would appreciate if you would send me the cut end as well

The pinout information you need can be found here:

I'd suggest you use a multimeter to work out which coloured wire connects to which pin. If you haven't got a multimeter then it's a fairly safe bet to assume that the red wire is +5V and the black one is ground. That then just leaves the clock and data wires. You have a 50/50 chance of connecting them correctly. However, you won't do any damage if you connect them the wrong way round.

Ah, kbdbabel.org has all the answers: http://www.kbdbabel.org/conn/index.html
I've connected the appropriate leads to a PS/2 cable using a bread board: Lo and behold, the old M is resurrected
(typing on it right now).
Ascaii, I'm still interested in your cable, I'll send you a PM.
